The Section 18A Receipt: What It Is, Who Needs One, and How to Not Get It Wrong
If your NPO relies on donations, you’ve probably heard donors ask for “an 18A certificate” without necessarily knowing what that means yourself. It’s worth understanding properly, because getting it wrong doesn’t just inconvenience your donor — it can put your organisation’s credibility, and their tax deduction, at risk.
What is Section 18A, in plain English?
Section 18A of the Income Tax Act allows a donor to deduct a bona fide donation from their taxable income — up to 10% of their taxable income per year — provided they hold a valid receipt from an organisation that SARS has specifically approved to issue them. It’s the mechanism that turns “thank you for your generosity” into “and here’s a tax benefit for it,” which is a genuinely powerful incentive for donor giving.
Here’s the catch: not every NPO or NPC can issue these receipts. Being registered as an NPO with the DSD, or even holding PBO status with SARS, doesn’t automatically give you the right to issue Section 18A receipts. That’s a separate approval, on top of PBO status, and your organisation needs to be conducting one of SARS’s recognised “public benefit activities” — welfare, healthcare, education, conservation, and land or housing development are the main categories that qualify.
What has to be on the receipt
SARS significantly tightened these requirements from 1 March 2026, and if your organisation hasn’t updated its receipt template since then, it’s worth checking now. A valid Section 18A receipt must include:
- Your organisation’s SARS reference number for Section 18A purposes
- Your organisation’s name and contact details
- The donor’s full details — including, now, whether they’re an individual, company, or trust, their ID or registration number, and their tax reference number
- The date and amount of the donation (or, for donations in kind, a description and fair market value)
- A unique receipt number
- Confirmation that the donation will be used exclusively for your approved public benefit activities
Missing any of this can mean the receipt is invalid — which means your donor’s deduction gets disallowed, and that’s not a conversation you want to have with a generous funder.
Doer vs conduit: a distinction worth knowing
If your organisation carries out the public benefit work itself, you’re a “doer.” If you instead pass donated funds on to other Section 18A-approved organisations to do the work, you’re a “conduit” — and conduits face extra rules, including a requirement to distribute at least half of receipted donations within 12 months of their financial year-end. Most grassroots NPOs are doers, but it’s worth knowing which one you are, especially if you ever partner with or fund another organisation.
Practical habits that keep you out of trouble
- Don’t issue a receipt before you’re approved. A receipt issued before SARS confirms your Section 18A reference number simply isn’t valid, no matter how well-intentioned the donation was.
- Keep a donation register, not just a spreadsheet of totals. You need to be able to match every receipt to a specific donor and donation, especially now that SARS requires more detailed reporting.
- Report to SARS, not just to your donors. Section 18A-approved organisations are required to submit regular data on the receipts they’ve issued, so SARS can cross-check what donors claim on their own tax returns.
- Ring-fence properly if you do mixed activities. If your organisation does both qualifying and non-qualifying public benefit work, you can only issue 18A receipts for donations used on the qualifying side — and you need records that clearly show which funds went where.
The bottom line
A Section 18A receipt is a small piece of paper carrying real legal weight — for your donor’s tax return and for your organisation’s credibility. Get the approval before you issue anything, keep the details complete and current, and treat your donation records as seriously as your bank statements. Your donors are trusting you with more than their money; they’re trusting you to get the paperwork right too.
